permission), try to continue in FTS_DONTCHDIR mode. Of course this
won't work for long paths, but we can't descend more than one pathname
component beyond the directory anyway if we lack search permission.
Here is a transcript demonstrating the change, where oldls is ls(1)
linked with the old fts(3):
das@VARK:~> mkdir t && touch t/{a,b,c} && chmod u-x t
das@VARK:~> oldls t
a b c
das@VARK:~> oldls -l t
das@VARK:~> \ls t
a b c
das@VARK:~> \ls -l t
ls: a: Permission denied
ls: b: Permission denied
ls: c: Permission denied
I had forgotten about this patch until bde reminded me. He reports
using it without problems for over a year.
